[80.01] Influence of Environments on Star Formation Properties of Galaxies

Y. Hashimoto (Yale U.), A. Oemler Jr. (Carnegie Obs.)

We have used 15749 galaxies in the Las Campanas
Redshift Survey, the largest imaging and spectroscopic
survey of nearby galaxies to date, to investigate the
influence of non-cluster environment on the star
formation properties of galaxies.

We find that environmental effects exist outside the
cluters, in such a way that galaxies at higher galaxy
densities exhibit reduced star formation compared
to the galaxies at lower density of the same
morphological type.
